AF speed is significantly improved from the current model, and it enables accurate high-speed focus even when capturing moving subjects.

When shooting with AF, the Full-time Manual Focus override allows you to instantly make fine-focusing adjustments manually, without having to switch between modes.

5. VC performance is now 4.5 stops and offers three modes optimized for different situationsThe VC (Vibration Compensation) effectiveness is equivalent to 4.5 stops, based on image stabilization performance levels established by CIPA (Camera & Imaging Products Association) when using VC MODE 3. Model A022 now has three types of VC modes, and it is possible to choose the optimum VC mode according to the situation for taking a photograph, such as when panning.

VC MODE 1 is the standard mode that strikes a great balance between the stability of the viewfinder image and the stabilization effects.

VC MODE 2 is exclusively used for panning.

VC MODE 3 prioritizes the stabilization of the captured images and forgoes the stabilization of the viewfinder image.

A new VC Mode can be programmed with the optional TAMRON TAP-in ConsoleTM. You can overwrite VC Mode 1 with a new VC Mode that allows stabilization to be engaged constantly for videography purposes. In this mode, the LCD screen is used.

6. New FLEX ZOOM LOCK mechanism enables locking of the zoom ring at any positionThe FLEX ZOOM LOCK mechanism quickly locks or unlocks the zoom at any position simply by sliding the zoom ring. Photographers can shoot from any angle without the zoom extending unintentionally. Additionally, the lens features the conventional Zoom Lock switch to prevent unwanted barrel extension during transportation.

7. Fluorine Coating and Moisture-Resistant Construction for a more user-friendly lensThe front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellent. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints. For greater protection when shooting outdoors, leak-proof seals throughout the lens barrel help protect your equipment.

8. Electromagnetic diaphragm system now used for Nikon-mount lensesAn electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses[1]. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

9. Lightweight and easy-to-hold tripod mount is compatible with an Arca-Swiss style quick release plateA new textured grip and Arca-Swiss style tripod interface enhances both speed and utility. And because the tripod mount is made of lightweight magnesium, it is much easier to carry.

10. Compatible with TAMRON TAP-in ConsoleTM, an optional accessory productThe optional TAP-in Console provides a USB connection to your personal computer, enabling you to easily update your lens’s firmware as well as customize features including fine adjustments to the AF and VC.

Detailed Feature Specifications

* VC (Vibration Compensation)VC is Tamron's proprietary image stabilization system. Tamron's VC employs a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three ceramic ball bearings. The VC lens elements are held in place only by contact with the ceramic ball bearings, achieving smooth movement with little friction. And since the VC mechanism is moved in parallel using only the motorized control, the mechanical structure has been simplified, enabling the development of more compact lenses. * The Ultrasonic MotorIn the ultrasonic motor, a piezoelectric element arranged in a ring formation generates ultrasonic vibrations in a metallic ring stator, and this vibration energy is used to rotate a metallic ring rotor that is attached to the stator. The rotation energy is in turn transferred from the metallic ring rotor to operate the focusing mechanism of the lens.

* eBAND (Extended Bandwidth & Angular-Dependency) CoatingeBAND Coating, developed by Tamron, is a new coating technique that radically improves anti-reflection properties. A nano-structured layer (1nm = 1/1,000,000mm), with dimensions smaller than the wavelengths of visible rays of light, is deployed on top of multiple coating layers to maximize light transmission efficiency.Reflections occur at the interface between the lens and the air because of the difference in refractive indices of the two substances. The nano-structure of the eBAND Coating makes possible an extremely low refractive index by minimizing the differential with that of air while actively inducing air to its own structure, thus significantly suppressing the extent and degree of reflections. In addition, the total anti-reflection efficiency at the lens surface is further improved by means of integrating the conventional coating technique based on an active utilization of the "interference of light" principle, attenuating the level of reflections by overlaying reflected light on the coating front surface and that of the back side with its phase shifted, thus increasing the net transmissivity.As a hybrid technology that integrates the newly developed nano-structured layer with an extremely low refractive index and conventional multiple-layer coatings, the eBAND Coating provides superb anti-reflection performance, delivering crisp, razor sharp images, and eliminating the flare and ghosting that can tangibly damage image quality to a remarkable degree.

Available from January 30, 2015 In limited quantities Suggested Retail Price: $1199 *The launch date of the Sony mount model will be announced at a later date.

I really don't understand why Tamron makes these announcements months before a new lens is even available. Perhaps they want to test the waters of public opinion. Either way, I've always welcomed their lenses - I own several and love using them. So I can't wait to get my hands on this potential beauty. Here's what I have on this lens for now, straight from Tamron.

November 7, 2013, Commack, N.Y. - Tamron Co., Ltd. (President & CEO: Morio Ono), a leading manufacturer of precision optics, has announced the development of an innovative ultra-telephoto zoom lens with a focal length range of 150mm to 600mm for full-frame and APS-C format DSLR cameras. The lens sample will be on display in the Tamron booth at the Salon de la Photo 2013 that will be held from November 7-11 in Paris, France. Pricing and delivery information are not available at this time.

4x ultra-telephoto zoom lens with a focal length range of 150mm to 600mmThe focal length range of this lens was extended by 50mm on the wide-angle side and 100mm on the telephoto side compared to the existing model A08, making it possible to take even more striking photographs of birds, wildlife, sports, and other distant subjects. Mounted on APS-C DSLR cameras, it has a stunning near1000mm telephoto equivalent focal length range of 233mm to 930mm.

World class image qualityEmploying 20 elements in 13 groups and boasting an advanced optical design, the lens delivers a superior balance of resolution and contrast for sharp, clear images. The front group contains three LD (Low Dispersion) glass elements (two in the first group, one in the third) for enhanced optical correction effectiveness, enabling the lens to thoroughly compensate for on-axis aberrations at the telephoto end. The lens also adopts eBAND Coating, developed from state-of-the-art coating technologies, and conventional BBAR (Broad-Band Anti-Reflection) Coating to greatly suppress ghosting and flare even when shooting under adverse lighting conditions.

Achieves a 600mm focal length in a compact easy-to-handle packageIngenious optical design features minimize the movement of lens groups within the lens when zooming. This reduces the amount of barrel extension needed to cover the complete focusing range, making the entire lens more compact.

Beautiful background blur effectsAdopting a 9 blade circular diaphragm enables users to create beautiful background blur effects (Bokeh), which provide even greater potential for creative expression. This circular diaphragm retains a nearly circular shape even at two stops down from its maximum aperture.

Comfortable autofocusTamron's new SP 150-600mm F/5-6.3 Di VC USD features a USD (Ultrasonic Silent Drive) ultrasonic motor drive for swift and accurate AF response, it delivers high torque, very fast response times, and very low noise. The full-time manual focus mechanism allows users to make fine manual focus adjustments at any time even when AF is engaged.

New elegant, high-class external finishTamron has upgraded the cosmetic design and finish of this lens to create a more sophisticated, high-end look in keeping with the demands of discerning full-frame DSLR users. Employing a sophisticated linear pattern rubber grip on the zoom and focus rings and an attractive and stylish tungsten silver brand ring, this newly designed model accentuates its visceral presence with understated elegance and class.

Comes with "SILKYPIX Developer Studio for Tamron", RAW image development processing software for Tamron's SP lensesThe SILKYPIX Developer Studio software can develop high-quality images from RAW data, incorporating adjustments that can express the personal style and taste of the photographer. These include white balance, color, sharpness, and the tonal curves recorded by digital cameras. The SILKYPIX Developer Studio for Tamron provides a range of functions, in addition to the basic adjustment capabilities, such as correcting aberrations (chromatic aberrations of magnification, distortion, peripheral light fall-off), based on the optical data. Used in tandem with Tamron's SP series lenses - renowned for their high-depiction capability - this advanced technology efficiently produces images that meet photographers' most exacting demands.
